Application April 2, 1953, Serial No. 346,421

3 Claims. (Cl. 57-151) This invention relates to a yarn with a decorative covering. It has formerly been the practice, when such a yarn was to be made, to twist a core member together with a covering member. Such practice was unsatisfactory in a number of ways.

I have discovered a new metallic yarn which is made in such a way that the core member is untwisted while the covering member is disposed about it and therefore permits the spiral eiect of the covering member to be controlled as well as the size of the nubs desired.

Briefly stated the invention comprises forming a yarn by moving a core member longitudinally and simultaneously wrapping a covering member about the core member. This wrapping process may be performed by either rotating the core member while the covering member is held in non-rotatable relationship or by rotating the covering member while the core member is held in non-rotatable relationship. Nubs may be produced on the yarn by slowing the longitudinal speed of the core member so that more of the covering member is wrapped about the core member at any specific point.

The invention will be further described by reference to the accompanying drawings which are made a part of this specication.

Fig. l is a front View of the principal form of the yarn made in accordance with this invention.

Fig. 2 is a greatly enlarged front View of the form of yarn shown in Fig. 1 showing the method of wrapping the covering member about the core member, the core member moving longitudinally in the direction of the arrow.

Fig. 3 is a sectional View of the yarn shown in Fig. 2 taken along lines 3 3 of Fig.v 2.

Fig. 4 is a sectional view of the yarn shown in Fig. 2 taken along lines 4 4 of Fig. 2.

Fig. 5 is a front view of an alternative form of the yarn made in accordance with this invention.

Fig. 6 is a greatly enlarged view of the form of yarn shown in Fig. 5 showing the method of wrapping the covering member about the core member, the core member moving longitudinally in the direction of the arrow and rotating in the direction of the arrow.

Fig. 7 is a sectional view of the yarn shown in Fig. 6 taken along lines 7 7 of Fig. 6.

Fig. 8 is a sectional ivew of the yarn shown in Fig. 6 taken along lines 8 8 of Fig. 6.

Referring to the form of the invention shown in Figs. 1, 2, 3, and 4, there is provided a core member 11 and a covering 12 disposed about the core member. Core member 11 is preferably formed of a plurality of strands 13 which may or may not be twisted together.

Covering 12 is preferably a metallic strip and is diS- posed about core member 11 in spiral relationship. Cov. ering 12 is formed in several thicknesses and spaced closely together at 16 so that decorative nubs are formed.

Core member 11 is also provided with fuzzy projections 17 secured to core member 11 of the conventional chenille type and covering member 12 cuts into the fuzzy Patented Sept. 24, 1957 ICC projections and bears against the body portion of core member 11.

Referring now to the form of the invention shown in Figs. 5, 6, 7, and 8 there is also provided core member 20. In this case, however, core member 20 is formed of a plurality of strands 21 which are formed into subelements 22 by being secured together by sub-coverings 23 and 24. Covering member 25 is disposed about core member 20 in spiral relationship and also forms nubs at 26.

Referring now to the method of making the yarn of this invention core member 11 or core member 20 is moved longitudinally as indicated by the arrows of Figs. 2 and 6. The core member is held by conventional devices. Covering member 12 or covering member 25 are wrapped about core members 11 or 20 while the core member is moving or, when nubs are to be produced, when the core member is either moved slowly or held in place. Covering members 12 or 25 are wrapped about core members 11 or 20 by two methods. As shown in Fig. 2 the core member is held steady and the covering member is rotated about the core member, the core member moving longitudinally at the same time. As shown in Fig. 6, however, the covering member may be held steady and the core member moved both longitudinally and rotatably to wrap the covering member about the core.

The core member may be either untwisted, as shown in Fig. 2 or twisted as shown in Fig. 6.

The foregoing specific embodiments of the invention as shown in the foregoing spec'iiication are for illustrative purposes and for purposes of example only. Various changes and modications may obviously be made within the spirit and scope of the invention and would occur to those skilled in this art.

I claim:

l. A decorative yarn comprising a plurality of core members twisted about one another, a separate first covering member twisted about each of said core members, and an additional covering member twisted about all of said core members under sufficient pressure to form a recess therein, said additional covering member also forming spaced nubs upon said twisted core members.

2. A decorative yarn comprising a plurality of core members twisted about one another, a separate first covering member of metallic material twisted about each of said core members and an additional covering member of metallic material twisted about all of said core members under suflicient pressure to form a recess therein, said additional covering member also forming spaced nubs upon said twisted core members.

3. A decorative yarn comprising a plurality of core members, each formed with a plurality of strands and twisted about one another; a separate irst covering member of metallic material twisted about each of said core members, and an additional covering member of metallic material twisted about all of said core members under suiiicient pressure to form a recess therein, said additional covering member also forming spaced nubs upon said twisted core members.
